		// resource that happens to have style information. Note the use of
		// CharSequence instead of String so we don't lose the style info.
		cs = getText(R.string.styled_text);

		// to lose the style information.
		str = getString(R.string.styled_text);
		tv = (TextView) findViewById(R.id.plain_text);
		tv.setText(str);

		// ====== Using the Resources object =================================

		// You might need to do this if your code is not in an activity.
		// For example View has a protected mContext field you can use.
		// In this case it's just 'this' since Activity is a context.
		Context context = this;

		// Get the Resources object from our context
		Resources res = context.getResources();

		// Get the string resource, like above.
		cs = res.getText(R.string.styled_text);
		tv = (TextView) findViewById(R.id.res1);
		tv.setText(cs);

		// Note that the Resources class has methods like getColor(),
		// getDimen(), getDrawable() because themes are stored in resources.
		// You can use them, but you might want to take a look at the view
		// examples to see how to make custom widgets.
